Called customer and he informed me that nobody will be home, gave me garage code. Upon arrival I found console unit in garage not running, breaker off. Turned breaker on and let system cycle on. Blower came on but breaker tripped immediately after compressor contactor pulled in, could hear compressor try to start for a split second. Removed compressor leads and found 91ohms at S-C, 321ohms at S-R, and .85ohms at R-C. Compressor is shorted and needs to be replaced. Kept compressor leads off and taped them so breaker doesn’t trip. Continued to run system until aux heat came on. Measured amps and heat rise to make sure it stays operational. Quoting customer to replace compressor. After speaking with customer via text, he asked me to keep the breaker off, doesn’t want aux heat to run. Put all wiring back on compressor and left breaker off.
